0J!" PATEBSON, NEW JERSEY, A CURPORATION FArSTENEBfSETTING MACHINE.

Patented Dec. 27, 1921.

Application filed Augmst 5, 1918. Serial No. 248,344.

To all whom it concern e it known that I, J osnrH GoUnDoURN, ai subjectof the K' of England, and resident oi' Leicesterjlfeicestershire,England, have invented certain Improvements in Fastener-SettingMachines, of which the fol-` lowingdescription, in connection with thefasteners to the settin mechanism, andhav-` ing, mechanismior ceding theworky step by step. 1

An object of the invention is to provide improved controlling meansadapted to control boththe fastener-supplying mechanism and thework-feeding mechanism, either coli lectively or individually, as thecase may be.

For purposes of illustration the invention isherein disclosed as` beingembodied in an eyeleting machine of which the eyelet-supplying mechanismmay be rendered inoperative temporarily, and of which the workfeedingmechanism may be` altered to increase or to decrease the length of the`steps.

. In some cases it is desirable t0 stop the supplying of eyelets whilethe machine continues to punch holes in and to feed the work with orwithout a change in the length of the feeding steps; On the other handit is sometimes desirable to change the length of the feeding stepswithout discontinuing the `United States No. 1,048,836 granted December31, 1912 on an application of A. E. "Jerram, but the controlling meansshown in .the latter patent would not be suitable for a machine havingwork-feeding mechanism of the type shown in the aforesaid Pearson atent.

The invention will be best understood trom` a consideration of thefollowing speci` licatlon taken in connection with the accompanyingdrawing, in which,-

Flgure 1 is a front elevation oit a machine embodying the presentinvention;

4 `Fig. 2 is a plan view partly in section of the right hand ond of themachine and shows the control mechanism;

Fig. 3 is a diagrammatic view showing the spacing mechanism; and

F 1g. l is a view ol the treadle controlled member.

Reference maybe had to the above-mentioned Jerram latent No. 1,048,836for a description oi parts not herein fully described but in generalsuch a machine will comprise a punch 10, setting devices 12, a hopperMaand a raceway 16. Movement of the various parts is effected from apower operated` shait 18.

The delivery of tasteners to the setting devices. is effected by meansof a spindle 20 irictionally mounted within the upper set 12 (see Fig. 6of the Jerram patent) and adapted to be projected through the endmostcyelet in the raceway 16 by means of aiinger 22 (sce Fig. 2). It will benoted that the end oil? this linger 22 which projects within the set'12is beveled at its upper side in order that no harm may result in casethe linger is projected into the set at the time the spindle 2O is inelevated position,l but the linger 22 will be pushed aside against theaction of a treadle spring 72 to be later described. Locking meanscomin-is ing a sliding pin 24 and an eccentric 26, operated by means ota handle 28, are provided for securing the linger 22 in its operativeposition, that is to say, in the position in which it will expel thespindle 2() dur-ing the retraction oi' the set. A lever 30 having a pinand slot connection with the linger 22 and loosely pivoted upon a verti-'cal shaft 32 journalcd in a bracket on the machine trame, is providedat one end with a member 311 provided with teeth arranged concentricwith the shaft 32 and for a purpose to be later described.

is in the arrangement oit the Jerram pat ent, the spacing oi the eyeletsis secured by feeding the work by means of a lateral movementl of apunch lever l0 carrying the punch l0. This lever -lO is mounted -forvertical movement within a iframe 42 which is pivotallymounted at 44-Vfor lateral movement about a pivotal axis. According to the presentinvention, this lateral movement is effected by transmitting themovement oli' a level` 426, pivoted at l? and operated from a cam lil,through two pivotallyconnected links a8. is in the arrangement ot' thePearson patent, the path or movement of the connecting point betweensaid linlrs is controlled by m s ot a link 50 which is mounted on apivot stud 52 carried by an arm 54 ined on the shalt 32 and having atoothed portion in the same plane as the toothed portion 3l ci the leverBO. The length ot the link 50 is equal to the distance between thecenters o'l the pivot 52 and the shalt 32.. Manual movement of the arm5/l to vary the position oi the stud 52 is secured by means ot a handlepinned to the upper end oi' the shaft 32 and movable over a perforatedplate into which Vpms 60 may be inserted ior limiting the movement oi"the handle 56. rlhe toothed portion of the arm is also concentric withthe shalt 32.

interposed between the toothed portion of the arm 54 and the toothedportion 34 is a pinion 62 meshing with said toothed portions andsupported for rotation within the forked end 6l of a rearwardlyextending rod 66. This rod is adapted to be manually actuated in one d''ection through a bellrcranlr lever'S by means of a rod 70 connected toa treadle or other suitable device (not shown) and in the otherdirection by a spring 7 2.

r" neither the finger 22 nor the handle 56 is locked in position, theoperator, without losing control of the work and while the machine is inoperation, may by depressing the treadle cause the forward movement ofthe pinion 62 to shift both the toothed arm 54 of the spacing mechanismand the toothed portion 34 ot the eyelet controlling mechanism so assimultaneously to increase the spacing between the punched holes and atthe same time to withdraw the finger 22 to prevent the ejection of thespindle 20 and hence to prevent the delivery of eyelets to the settingmechanism. It, however, either one of these toothed arms is locked inposition or reaches its limiting position before the other, the pinion62 will roll upon the locked arm and cause movement of the other armthereby to control that mechanism which is unlocked. Upon release of thetreadle, the spring 72 will. cause retraction ot` the pinion 62 andreverse the operation.

It will be understood that, although the invention has been illustratedand described in connection with a particular machine and particularcontrol mechanisms, its use 1s not so limited and it can be applied toother similar machines to effect similar results.
